Product Description
The Simpson ATR 7/8 in. x 18 in. Zinc-Plated All-Thread Rod from Simpson is a fully threaded tension transfer element engineered for use with Simpson Strong-Tie adhesives. Threaded along its entire length, this zinc-plated steel rod is built for structural applications including floor-to-floor holdowns and a broad range of anchoring solutions, delivering the reliability and versatility that demanding structural work requires.
Key Features
- Fully threaded along the entire length - gives you maximum flexibility in positioning and depth when working with adhesive anchoring systems and structural connections
- Cut to length for convenience - allows the rod to be trimmed on-site to fit your specific application without needing a custom-ordered size
- Zinc-plated steel construction - provides a corrosion-resistant finish suited for a variety of interior structural applications
- UNC Class 2A or 1A thread specifications - ensures compatibility with standard UNC-threaded hardware, simplifying assembly and hardware sourcing
- 7/8 in. diameter and 18 in. length - sized for structural-grade anchoring tasks where a robust, full-length threaded rod is required
Why This Product
- Designed as a true tension transfer element - the ATR is purpose-built for use with Simpson Strong-Tie adhesives, making it a natural fit for engineered holdown systems and adhesive anchor applications rather than a generic off-the-shelf rod
- Full-length threading means no wasted rod - because every inch is threaded, you can cut the rod to your needed length without losing usable thread, reducing waste and increasing adaptability across multiple project types
- Two available finish options suit different project conditions - the zinc-plated finish is one of two coatings offered in the ATR line, giving contractors the ability to match the rod to the exposure and performance requirements of their specific application
- Made in the United States by a trusted structural brand - the ATR rod is a Simpson product manufactured domestically, supporting quality consistency for structural and anchoring applications where performance matters
